尤里卡表格：如何更改表格的整体色彩

Question

我正在使用Eureka在我的项目中实现一个简单的表单。键盘上方的色带按钮中的表单似乎带有蓝色，我不确定如何更改它。

有没有办法像我的UI其余部分一样使“完成”标签变为绿色？

Answer 1

更新了Eureka 4.3.x

您应该在控制器中覆盖变量 customNavigationAccessoryView

override var customNavigationAccessoryView: (UIView & NavigationAccessory)? {
    // The width might not be correctly defined yet: (Normally you can use UIScreen.main.bounds)
    let navView = NavigationAccessoryView(frame: CGRect(x: 0, y: 0, width: view.frame.width, height: 44.0))
    navView.barTintColor = UIColor.MaterialColors.category3
    navView.tintColor = UIColor.white
    return navView
}

在这里，您要修复完成标签的颜色。 将NaviagtionAccessoryView实例替换为下面的navigationAccessoryView

navigationAccessoryView.tintColor = "Your Colour"
navigationAccessoryView.backgroundColor = "Your Colour"
navigationAccessoryView.doneButton.tintColor = "Your Colour"

您可以通过以下方式为所有UIView实例设置默认的颜色：

UIView.appearance().tintColor = .red

appearance（）是UIAppearance协议中的一种方法。 UIView及其子类对此协议进行了确认。您也可以

UIButton.appearance().tintColor = .green

Answer 3

在AppDelegate中添加以下行

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool 
{
   self.window?.tintColor = UIColor.black // You can set it to which color you want.
   return true
}

整个应用程序的所有色调都会更改为给定的颜色。

这完全适合我：

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    NavigationAccessoryView.appearance().tintColor = /* your color here */
}
